What memories of Lanzhou City Wall and Gate in 1920s

This is a group of photos taken at the gate of Lanzhou City Wall in 1920s by Father Di Huachun. Of course, these city walls and gates no longer exist. Let’s use this group of old photos to remember the past history and memories

In the third year of Emperor Wen of the Sui Dynasty (583), Jincheng Prefecture was changed into Lanzhou and the general administration office was set up. Because there is Gaolan Mountain in the south of the city, it is named Lanzhou. Lanzhou was built many times before the Ming Dynasty. By the early Ming Dynasty, Lanzhou had built an inner city. During the reign of Xuande in the Ming Dynasty (1426 AD— 1435 AD), the Outer City was built with an irregular circumference of 18 li and 120 paces. Since then, Lanzhou City has begun to take shape. In the Qing Dynasty, the city gates and walls were wrapped in bricks. In the Republic of China, the four gates of the inner city were called the East West North South Gate respectively

中山桥，现在还保存着。

现代的中山桥

兰州内城周围六里二百步(每步为五尺)，呈东西略长的矩形。城墙高三丈五尺，宽二丈六尺。有四门：东曰承恩门(后改为来煦门)，西曰永宁门(后改为镇远门)，南曰崇武门(后改皋兰门)，北曰广源门(俗称水北门)。
